Home Extensions

Isn’t it time you gifted yourself more space?

You don’t necessarily need to move house if you want more space, but you’re perfectly content with where you currently reside. The installation of a single-storey extension can be an affordable way of expanding the property, and comes without the inevitable upheaval involved in relocating.

Built completely from scratch, you could easily have an extension that provides you with a study so that you can easily work away from the office or add an extra bedroom to enable more people to stay over.

James Oliver has a wealth of options in terms of windows, doors, walls and pillars to help you get an extension that brilliantly caters for everything you want and becomes a real focal point of the house.

Stylish, affordable, simple.


We have a unique approach to building extensions…

James Oliver is capable of doing everything, so you won’t need to go out and find an expensive builder, architect, plumber, plaster and fitter. We also promise to meet important deadlines and stick to your budget.

Full project management is offered by James Oliver, which will save you a lot of money, and a lot of time.

  • Dream Big - You will be able to watch your new extension come together on our hi-tech 3D software in our showroom. It will enable you to envisage the finished design, internally and externally, ahead of commissioning the final build.
  • Hassle Free - We will save you the hassle of applying for planning permission and / or building regulations approval, if it’s required, by organising it for you.
  • Huge Choice - You have an overwhelming amount of choice, including several roofing options (traditional tile or slate to modern composite), standard or vaulted ceilings, and various window and door styles.
  • Feel Involved - You won’t feel uninformed during the building process. We will ensure you have a heavy involvement in things.
  • Surprisingly Affordable - It might be handy for you to be able to spread the cost of the extension over several years, rather than pay upfront. We’ll have a form of finance that suits.
